Bothan

A Ruby client for Bothan, a simple platform for storing and publishing metrics.

Installation

Add this line to your application's Gemfile:

gem 'bothan'

And then execute:

$ bundle

Or install it yourself as:

$ gem install bothan

Usage

First require the Bothan client:

require 'bothan'

Then initialize a connection with your username, password and the url of your Bothan endpoint:

@bothan = Bothan::Connection.new('username', 'password', 'https://demo.bothan.io')

You will then be able to interact with your Bothan API via the metrics method like so:

Get all metrics

Returns a list of available metrics as an array of hashes

@bothan.metrics.all
#=> [{"name"=>"metric-with-geodata", "url"=>"https://demo.bothan.io/metrics/metric-with-geodata.json"}, {"name"=>"metric-with-multiple-values", "url"=>"https://demo.bothan.io/metrics/metric-with-multiple-values.json"}, {"name"=>"metric-with-target", "url"=>"https://demo.bothan.io/metrics/metric-with-target.json"}, {"name"=>"metric-with-ytd-target", "url"=>"https://demo.bothan.io/metrics/metric-with-ytd-target.json"},{"name"=>"simple-metric", "url"=>"https://demo.bothan.io/metrics/simple-metric.json"}]

Find a metric

Latest value

Returns the latest value for a specified metric as a hash

@bothan.metrics.find('simple-metric')
#=> {"_id"=>{"$oid"=>"58451086db72110004125f6d"}, "name"=>"simple-metric", "time"=>"2016-12-05T07:00:22.459+00:00", "value"=>68}

For a specific DateTime

Returns the most recent value of a metric at the specified datetime.

@bothan.metrics.find('simple-metric', '2016-12-05T07:00:22.459+00:00')
#=> {"_id"=>{"$oid"=>"58451086db72110004125f6d"}, "name"=>"simple-metric", "time"=>"2016-12-05T07:00:22.459+00:00", "value"=>68}

For a specific DateTime range

Returns all values of the metric between the specified times.

@bothan.metrics.find('simple-metric', '2016-12-01T07:00:22.851+00:00', '2016-12-05T07:00:22.459+00:00')
#=> [{"time"=>"2016-12-01T07:00:22.851+00:00", "value"=>92}, {"time"=>"2016-12-02T07:00:22.759+00:00", "value"=>17}, {"time"=>"2016-12-03T07:00:22.664+00:00", "value"=>18}, {"time"=>"2016-12-04T07:00:22.569+00:00", "value"=>12}, {"time"=>"2016-12-05T07:00:22.459+00:00", "value"=>68}]

The from and to values can be either:

• An ISO8601 date/time
• A Ruby DateTime object
• An ISO8601 duration
• *, meaning unspecified

Create a metric

The Bothan API supports four types of metric, all supported by the gem.

Create a simple metric

# Create a metric called 'my-new-metric' with a value of '12' at the current datetime
@bothan.metrics.create('my-new-metric', 12)
# Create a metric with a specific datetime
@bothan.metrics.create('my-new-metric', 12, '2016-01-01T00:00:00')

Create a metric with a target

# Create a metric called 'my-new-metric' with a value of '1091000', an annual target of '2862000' and a ytd target of '1368000' at the current datetime
@bothan.metrics.create_target('my-new-target-metric', 1091000, 2862000, 1368000)
# Create a metric with a target at a specific datetime
@bothan.metrics.create_target('my-new-target-metric', 1091000, 2862000, 1368000, '2016-01-01T00:00:00')
# Create a metric without a ytd target
@bothan.metrics.create_target('my-new-target-metric', 1091000, 2862000)
# Create a metric without a ytd target at a specific datetime
@bothan.metrics.create_target('my-new-target-metric', 1091000, 2862000, nil, '2016-01-01T00:00:00')

Create a metric with multiple values

# Create a metric called 'my-new-metric' with multiple values with the current datetime
@bothan.metrics.create_multiple('my-awesome-mulitple-metric', {
  "value1" => 123,
  "value2" => 23213,
  "value4" => 1235
})
# Create a metric called 'my-new-metric' with multiple values with a specific datetime
@bothan.metrics.create_multiple('my-awesome-mulitple-metric', {
  "value1" => 123,
  "value2" => 23213,
  "value4" => 1235
}, "2016-11-28T09:00:00")

Create a metric with geodata

# Create a geodata metric called 'my-new-metric' with the current datetime
@bothan.metrics.create_geo('my-new-metric', [
  {
    "type" => "Feature",
    "geometry" => {
      "type" => "Point",
      "coordinates" => [-2.6156582783015017, 54.3497405310758]
    }
  },
  {
    "type" => "Feature",
    "geometry" => {
      "type" => "Point",
       "coordinates" => [-6.731370299641439, 55.856756177781186]
    }
  }
])
# Create a geodata metric called 'my-new-metric' with a specific datetime
@bothan.metrics.create_geo('my-awesome-geo-metric', [
  {
    "type" => "Feature",
    "geometry" => {
      "type" => "Point",
      "coordinates" => [-2.6156582783015017, 54.3497405310758]
    }
  },
  {
    "type" => "Feature",
    "geometry" => {
      "type" => "Point",
       "coordinates" => [-6.731370299641439, 55.856756177781186]
    }
  }
], "2016-11-28T09:00:00")

Development

After checking out the repo, run bin/setup to install dependencies. Then, run rake spec to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
